Respondents were asked questions regarding exposures to violence, social cohesion, access to services, and household assets. Household assets were categorized as medium assets (bed, fridge, and washing machine) and extended assets (mobile phone, internet access, radio, computer, microwave, heater, car, and television) per the UNHCR Vulnerability Assessment [30].
The 22-item Impact of Event Scale-Revised (IES-R) based on a Likert scale of 0 (not at all) to 4 (in full) was used as a validated instrument to estimate subjective distress and calculate a distress score. Possible scores ranged from 0 to 88, and a score of greater than 33 has been established to be have high diagnostic accuracy for PTSD [31, 32].
